In Great: Britain February 2, 1938 v I 13 Claims. (01.12-315) This invention relates to machines for beveling the rear ends of attached soles of shoes in'the manner disclosed in United States Letters Patent No. 2,027,431, granted Januarygl l, 1936, upon an application filed in the names bf Hazelton, James and Bacon, for reception in V-shaped channels formed in the breasts" of built-in) leather heels to be attached to the shoes.

It is an object of the present invention to provide an improved machine of the same general type as that disclosed in United States Letters Patent No. 2,017,151, granted October 15,1935,

on an application filed in the names of Hazel- In order to form attractive joints between the upper breast corners. of the heel and the sole of a shoe such as disclosed in United States Letters Patent No, 2,027,431, the lateral margins of the beveled rear end of the sole should extend to butnot forwardly of the heel-breast line. Accordingly, the width of the lateral margins of the bevel at the rear end of the attached sole of the shoe should be approximately equal to the depth of the end portions of the V-shaped channel formed in the breast of the heel, irrespective of the Qthickness of the sole. The lateral portions of the /-shaped sole-receiving channels formed in the breasts of heels of different sizes are of. uniformdepth and accordingly it is desirable that the lateral margins of the bevel formed on the attached sole shall be of thesame width regardless of the thickness of the sole.

With the abovefobject and considerations in view, and in accordance with a feature of this invention, there is provided a sole-fitting machine comprising a support for the rear end of a sole, a knife having a cutting edge, means for initially moving the knife to cause said cutting edge to be forced against one face ofthe sole, and means for. imparting a second movement to the knife in a path which is disposed at an angle to said one face and extends from said one face of the sole to the other thereby trimming material from the sole by abeveling cut.

The sole support of the illustrated machine has the form of a cutting bed which is interposed between the rear end of an attached sole of a shoe and the bottom of the shoe and which has a shear edge past which the cutting edge of the knife reciprocates. The knife, and a carrier having a guideway in which the knife is reciprocated to trim the sole, are mounted'for pivotal movement together about an axis which is coincident with the shear edge of the cutting. bed, the arrangement being such that theiretracted knife which is in a raised position above the cutting bed when the machine is idle, is swung bodily downward about said axis until its cutting edge is forced against the outer face of the sole preparatory to trimming the sole. knife is then moved forwardly in the guideway of the carrier, the cutting edge of the same traveling'from the outer to the inner face of the rear end of the attached sole of the shoe and past the shear edge of the cutting bed to trim material from the sole by a beveling cut. It will be appreciated that in making the beveling cut the cutting edge of the knife travels the same distance through the soleregardless of the thickness of the same, since the distance between the shear edge of the cutting bed and the line of engagement of the cutting edge of the knife, when it is initially swung against the sole as above described, is always the same. Accordingly, the beveling cut is always of the same width regardless of the thickness of the sole, the width of the out being approximately equal to the depth of the lateral portions of theV-shaped sole-' receiving channel formed in the breast of the heel. It will be noted that'although the width of the beveling cut is constant, the angle of the bevel varies in accordance with the thickness of the sole. However, since the heel is compressed slightly during the heel-attaching operation, the sides of the V-shaped channel formed in the breast of the heel are forced effectively against the beveled portion of the sole irrespective of the angle of the beveling cut.

The various features of the invention will be understood and appreciated from the following detailed description read in connection with the accompanying drawings, in which Fig. l is a side view, partly in section and partly broken away, of an illustrative machine;

The illustrated machine is described with refconstruction areset forth in the above-mentioned United States Letters Patent No. 2,027,431.

The illustrated machine, which is similar in many respects to the machine disclosed in the above-mentioned United States Letters Patent No. 2,017,151, is provided with a jack 32 (Fig. 1) comprising a shoe supporting plate 34 which, as .viewed in plan, has an outline similar to that of the heel end'of the insole of the shoe, and a post 36 (Fig. 1) into which a depending extension of plate 34 is threaded. The post 36 is slidable in a cylindrical bore 38 of a pedestal 40 and has a slot 42 through which passes a screw 44 threaded into the pedestal. When the machine is idle the post 36 is held ina raised position by a spring 46 which fits in a bore of the post and has its lower end resting upon the screw 44.

The pedestal 46 is mounted for sliding movement in a guideway 48 (Figs. 1 and 2) formed in a forwardly projecting flange of the machine frame 54, the arrangement being such that the jack is moved forwardly to a loading position to place the shoe upon the jack and is then moved rearwardlyuntil the rear end of the shoe engages a backgage 52 (Figs. 1 and 3).

The back gage 52 may be moved into different operative positions along a guideway 54 (Fig. 3) in accordance with the length of a heel which is to be attached to the shoe, and is measured in a heel gage (not shown). The heel gage, the back gage, and mechanism for operatively connecting said gages are similar to corresponding means disclosed in United States Letters Patent No. 1,847,244, granted March 1, 1932, on an application filed in the names of Hazleton and Ricks, and need not be further described herein. Secured to the back gage by screws 55 (Fig. 3) is a forwardly projecting finger 56 which is arranged to overlie the bottom of the positioned shoe, and prevents the rear end of the shoe from being tipped upwardly by the operator.

1 As the shoe mounted upon the jack 32 is moved rearwardly along the guideway 48, the rear end 58 (Figs. 3 and 8) of the attached sole of the shoe is guided over a wedge-shaped cutting bed or sole support 66 and under a straight cutting edge 62 (Figs. 4 to 7) of a knife 64 which, when the machine is idle is in its raised position shown in Fig. 5. After the shoe has been moved into engagement with the back gage 52 the operator depresses a treadle 66 (Fig. 1) causing, through mechanism which will be described later, the for- Ward end of a lever 68 to move the post 36 upward, thereby forcing the heel end of the shoe bottom against the lower face 16 of the. cuttin bed 60. The cutting bed is secured to the main frame 50 by a pair of screws 12 (Fig. 3) which pass through elongated openings 14 in the main frame and are threaded into depending flanges 16, respectively, at opposite sides of the cutting bed 60. It will be noted (Fig. 3) that the lower face 19 of the cutting bed 6|] is in alinement with the shoe-engaging face-of the finger 66 which is secured to the back gage 52.

The lever 68 (Fig. 1) through which the shoe is raised, is pivoted at 18 to the main frame 66, and has its front end constantly urged downward by a spring 80. The rear end of the lever 68 is connected by a vertical link 82 to a horizontal link 84, the forward end of which is pivoted to a rod 86. A rod 81 is connected at its lower end to the treadle 66 and at its upper end to a central portion of the link 64. As will appear presently, by lowering the rod 86 (Figs. 1 and 3) the cutting edge 62 of the knife 64 is swung into engagement with the heel end 58 of the solesupported by the cutting bed 66, as illustrated in Fig. 6, preparatory to moving the knife forwardly and downwardly in a rectilinear path to trim the sole by the beveling cut 26 (Figs. 7, 8 and 10). When the treadle 66 is first depressed by the operator the link 84 is moved in a counterclockwise direction about the vertical link 82 causing, through mechanism which will be described later, the knife to be swungbodily from its raised position shown in Fig. 5 into engagement with the sole mounted upon the cutting bed 66, as illustrated in Fig. 6. Upon continued depression of the treadle 66 (Fig. 1) the link 84 is moved in a clockwise direction about the rod 86 causing the overlasted counter portion of the shoe upper to be forced against the lower face 16 of the cutting bed 60 thereby clamping the shoe against movement in the machine.

The end portions of channels 36 (Fig. 9) formed in the breasts of heels 24 of different sizes are usually of the same depth. It will be appreciated that in order to obtain an attractive joint between the upper breast corners of the heel and the sole of the finished shoe, the lateral margins of the beveled rear end 28 of the sole should extend to but not forwardly of the heel-breast line 88 (Fig. 8). Accordingly, it is desired that the width of the lateral margins of the beveled portion 26 of the sole shall be approximately equal to the depth of the end portions of the channel 39 irrespective of the thickness of the sole. It will be appreciated that the heel is compressed slightly during the heel-attaching operation with the result that in the finished shoe the sides of the V-shaped channel are effectively forced snugly against the beveled rear end 28 of the sole, irrespective of the angle of the beveling cut 26.

The cutting bed 60 has a serrated face 99 (Figs. 4 to 7) against which the sole is forced by presser rolls 92 which, as will appear later, move with and ahead of the knife64 during its trimming movement. Extending from one side of the cutting bed 60 to the other is a cylindrical groove 94 (Figs. 4 to 7). The knife 64 is moved forwardly and downwardly to make the beveling cut 26 until its cutting edge 62 has moved to a position just forward of an edge 96 formed by the intersection of the groove 94 and a smooth portion of the face of the cutting bed 60, as illustrated in Fig. 7. It will be noted that the forward portion 98 (Figs. 6 and '7) of the cutting bed 69 serves to support portions of the sole which are located a short distance ahead of the breast line 8 (Fig. 8) against being depressed by the action of the knife 64. With such an arrangement it has been found that the knife 64 severs the sole with a clean cut at the edge 96 of the cutting block 63, which edge may be referred to as a shear edge.

The knife 34 is secured in a groove I03 (Fig. 3) of a slide IE2 by a bolt I04 which. passes through an open-ended slot I86 of the knife and fits in alinedcylindrical bores in the slide I32, a plate II'IB which is secured by screws H19 to the slide, and .an upstanding bracket III), the bolt Hi4 beingclamped against the under side of the knife through the provision of a nut I I2 threaded onto the upper end of the bolt. It will be understood that since the slide II'IZ is normally secured to the knife 64 it may be considered as constituting Dart thereof.

The attached soles of shoes are of varying thicknesses and, accordingly, it is desirable to paratory to trimming the sole by the beveling swing the retracted knife 64 about an axis II4 (Figs. 2 and 4) which is coincident with the shear edge 36 so that the cutting edge 62 of the knife can be moved from the position illustratedin Fig. 5 into engagement with the sole (Fig. 6) precut (Fig. 7). It W111 be appreciated that if the cuttingedge 62 of the knife 64 were not swung into engagement with the sole, as above described,

before reciprocating the knife to trim the sole,

the beveled rear ends 28 of the soles would be of varying widths in accordance with the thickness of the sole and would therefore not be of a uniform width equal to the depth of the lateral margins of the channel 30 formed in the breast of the heel. I

When the machine is idle the knife 64 occupies a position in which its cutting edge 62 is located well above the cutting block (it), as shown in Fig. 5, thereby providing a gap IIIS which is wide enough to receive the rear end 53 of the attached sole of the shoe being positioned in the machine. In order initially to swing the cutting edge 62 of the knife I54 against the sole as above described, the slide I02, which is mounted for movement in a rectilinear guideway II8 (Fig; 3) of a carrier I23, is mounted for swinging movement, together with the carrier, upon hearing pins I22 supported by the main frame 50, the axes of the pins I22 being coincident with the axis H4, which. as above stated, extends along the shear edge (-33 of the cutting bed 60.

The slide I 92 has at its rear central portion apair of spaced bosses I24 (Figs. 2 and 3) in which is secured a rod I26 (Fig. 3). Mounted upon the rod I23 is a sleeve or cam roll I28 fitting in anlarcuate slot I3!) formed in an upstanding flange ISZWFigs. 2 and 3) of an operating slide I34 which is movable along a rectilinear guideway I33 (Fig. 3) of a bracket I38 (Fig. 2 and 3). The bracket I38 is mounted upon shafts I40 supported by the main frame 5!) and may be initially swung about the shafts to insure that the arcuate guideway I33 (Fig. 3) is centered about the axis I I4 (Figs. 2 and 4) through the following arrangement. Located at opposite sides of the bracket I38 (Figs. 2 and 3) are two bores into which are threaded sleeves I42. Passing through openings in the respective sleeves I42 (Fig. 3) are screws I44 which are threaded into the main frame 55). The screws I44 are normally tightened so that the bracket I38 is held fixed, clockwise movement of the bracket about the shafts I4I) being prevented by the engagement of the sleeves I 42 with the main frame 50, and movement of the bracket I33 in a counterclockwise direction being prevented by washers I46 which are interposed between the bracketand the heads of the screws I44. j 1

The operating slide I 34 has a pair of downward ly projecting bossesI48 bored to receive a pin I50 connectingthe slide I34 to a link I52. The rear endof the link I52 is pivoted to a pin I54 which is secured to a block I 5| fitting in an areaate slot I53 of a driving link I55. The block I5I is carriedby a yoke I56 and may be secured in different adjusted positions along the slot I53 through the provision of a screw I58 which is ping a clutch I'I6(Fig. 1) the shaft I14 is rotated through a complete revolution and then comes to rest.

When the machine is idle the cam roll I28 (Fig..

3) which is secured for movement with the knife 64, as above described, is forced against the upper end of the slot I through the provision of a pair of connecting'links I III (Figs. 1 and 3) pivoted upon pins I19 secured to opposite sides of the carrier I20. Mounted upon a rod IBI) (Fig. 3) secured to the lower ends of the links H8 is a sleeve IBI having depending flanges I82 which straddle and are pivoted to the upper end of the rod 86.

The rod 83" is normally urged upwardly through the link 84 and the treadle rod 81 by a spring I84 (Fig. 1) the lower end of which is secured to the treadle 63 and the upper end of which is secured to the main frame. When the sleeve I28 (Fig. 3) carried by the slide I02 is in engagement "with the upper end-of the slot I33 the knife 64 is in its raised position shown in Fig. 5 above the cutting bed 60.

In order to insure accurate control of the beveling cut 26 (Figs. 7, 8 and 10) the machine is provided with the above-mentioned rolls 92 which advance with the knife 64 and press on the outer face of the attached sole of the shoe, one at each side thereof just in front of the cutting edge 62 of the knife. The rolls 92 are yieldable upward in paths disposed at approximately right angles to the line of the cut and insure against the knife 64 picking up the sole as it trims the same.

The upstanding bracket I III (Figs. 2 and 3) has a rearwardly extending lug I36 to which is secured a laterally extending pin I 33 normally fitting in open-ended slots IIII.) (Fig. 3) of two upstanding flanges I92 (Figs. 2 and 3) formed integral with the plate IIJII, which, as above stated, is secured by the screws I09 to the slide I32. With the above arrangement the bracket IIII may be quickly and accurately positioned upon the plate I03. The bracket I III has pivoted to it right and left pairs of parallel links I94 2 and 3) I36 (Fig. 3) the forward end portions of which pairs are pivoted in bifurcated portions of corresponding blocks I98 (Figs. 2 and 3) one carried of an adjacent link I96. The arrangement is such that the springs 206 constantly urge. the blocks I98 downward in paths disposed at right angles to the direction of movement of the knife-carrying slide I02, the degree of compression of the springs 206 being regulated by adjusting the screws 202 in the flanges 200. Downward movement of the blocks I98 is limited by the engagement of rearward extensions 2I0 of the respective links I94 with stop screws 2I2 threaded into a rearwardly extending portion of the flange 200. The idle positions of the blocks I98 maybe raised or lowered by altering the setting of the screws 2I2 in the flange 200. I

In the forward face of each of the blocks I98 is a horizontal T-shaped channel 2I6 (Fig. 3) and in each channel is a T-shaped slide 2 I 6 into which is threaded a locking screw 220 (Figs. 2 and 3) for normally retaining the slide in a fixed position in the channel. When the screws 220 are released the T-shaped slides 2 I8 may be adjusted in their corresponding T-shaped channels 2I6. The locking screws 220 fit in bores of correspond- ,ing roll carriers 222 and are provided with lock.

nuts 224 which normally clamp the roll carriers fast to their corresponding T-shaped slides 2I8, but which may be released preparatory to varying the angular positions of the roll carrier's 222i upon the slides. The lower end portions of the roll carriers 222 are bifurcated, as shown in Fig. 4, and carry pins 226, respectively, (Figs. 2 and 4) on which the corresponding rolls 92 are rotatably mounted. The presser rolls 92 are located just above the cutting edge of the knife 64 (Figs. 4 to '7) and their axes lie in a plane which is approximately perpendicular to the direction of movement of the knife-carrying slide I02. The rolls 92 are cylindrical and are conveniently about one-half an inch in length and diameter.

It will be appreciated that the positions of the presser rolls 92 can be adjusted lengthwise of the cutting edge 62 of the knife 64 and that the angular positions of the rolls can be adjusted in a plane arranged at right angles to the direction of the cutting stroke of the knife. Moreover, the rolls 92 can yield upwardly away from the cutting edge of the knife during the cutting stroke of the same, the degree of compression of the springs being initially regulated through the provision of the set screws 202. As the cutting edge 62 of the knife 64 advances into the sole the presser rolls 92 traveling with the knife engage the upper surface of the sole at each side thereof and press the sole firmly against the serrated upper face 90 of the cutting bed 60, the beveled rear end 28 of the sole passing between the knife and the rolls, as illustrated in Fig. 7. The chip 228 severed from the sole is left between the lower surface of the knife 64 and the serrated face 90 of the cutting bed 60.

In order to trim the rear end 58 (Fig. 8) of the attached sole 20 of the shoe 22 by the beveling cut 26 (Figs. 7, 8 and for the reception of the heel 24, the operator places the shoe upon the jack and slides the jack with the shoe mounted on it rearward, the rear end 58 of the sole being fed over the cutting bed 60 until the rear end of the shoe engages the back gage 52. The operator then depresses the treadle 66 causing the knife 64, together with the carrier I02 in which the knife reciprocates, to be swung bodily downward about the axis I I4 until the cutting edge 96 of the knife has been forced against the sole, as shown in Fig. 6, further depression of the treadle 66 causing the jack 32 to be raised and thereby to force the overlasted counter portion of the shoe upper against the lower face 10 of the cutting bed 60. The onerevolution clutch "6 (Fig. 1) is then tripped, causing the knife 64 to be moved forwardly and downwardly past the shear edge 96 of the cutting bed 60 to the position illustrated in Fig. '7, to trim the sole by the .beveling cut 26. The operator then releases the treadle 66 and, after moving the I jack to its forward loading position, removes the shoe from the jack.
